1. PLANNING INFORMATION

A. Effectivity

BD−100−1A10 aircraft, Serial No. 20003 to 20500.

NOTE: The instructions given in this Service Bulletin are only applicable to the

systems and parts installed at the time of delivery of the aircraft or as

changed by Bombardier Aerospace Service Bulletin(s).

Before you do this bulletin, examine all STC, STA or equivalent action

changes to make sure that this bulletin can be completed.

B. Reason

The current Pitot−Static probe heater design may exhibit a failure which results in

the heating function to remain ON when not selected and the heating performance

may also be degraded. The new Pitot−Static Probe heater provides a more robust

design that will prevent these failure cases to occur.
